Having experienced a lot of fun at the VIR event and being very impressed with every aspect of it, it was painful not being at the Glen race. For me, that long trip was just too far for my budget. I'm hoping 2012 will include Rd Atl and other southeastern tracks.
Perhaps FF racers who are not as fast as many of the pro F1600 drivers, are worried about being on pace. The talent and quality of competitors in the series is jaw dropping. However, I would encourage local racers to join the series when it's nearby. It will be an experience you'll cherish forever. One of the great parts of the series is a full field, with plenty of competition throughout the field. Plus, I think they'll waive the series fee for your first race (if you may not do more).
For all of you who raced at the Glen - Congratulations. From tweets, race reports and apexspeed posts, it sounds like it was even more competitive than VIR.
